A T TORNEY Patented Apr. 11, 1939 UNITED STATES PATENT OFFICE 3 Claims.

The invention relates to a cooking kit which includes a spirit burner, a plurality of cooking utensils, and a support means for disposing a selected utensil for its heating by the burner.

An object of the invention is to provide a cooking'kit of the class described wherein the various elements are arranged for a packed association to provide a particularly compact cooking kit package.

;Another object is to provide a kit of the class described wherein cooking utensil elements thereof provide a sealed exterior for the packaged kitwhile enclosing the burner and other kit elements.

Afurther object is to provide a support for. the cooking utensils which removably engages a utensil mounted thereon-against lateral displacement in its place.

Yet another object is to provide a utensil support which is arranged to simultaneously provide a shielding and draft-controllingenclosure for theburner element while the same is in use beneath a utensil of the kit.

'The invention possesses other objects and features-of advantage, some of which, with the foregoing, will be set forth or be apparent in the following description of a typical embodiment of the invention, and in the accompanying drawings, in which,

Figure 8 is a'sectional elevation of kit elements wherein adiiferent pan element of the kit than that shown in Figure 2 is mounted for heating, and the burner element is shown in section.

Figure 9 is a stepped plan section taken at the broken line '9-9 in Figure 8,

U @The illustrated cooking. kit comprises pan 05, elements |2 and I3 and M, a burner element I5,

and members It and l! which are arranged to cooperatively provide a generally tubular structure |8 for supporting one of the pan elements while supporting and enclosing the burnerelement I5. In plan, the aforesaid elements may be circularor oval; in the present showing, these elements are circular.

The pan i2 is relatively shallow, and, for reasons will hereinafter become apparent has a stepped side wall whereby the pan has a circular bottom 2| and an annular portion. 22 parallel to said bottom, and the pan side wall has lower and upper portions 23 and 24 which are coterminous with the portion 22 at the different boundaries thereof. As shown, the lower wall portion 23 is curved into tangential relation with the bottomportion 2| whereby to avoid a sharp corner at the juncture of the wall and bottom portions and provide a generally tapered pan bottom portion. ,An outturned bead 25 is provided at the free edge of the upper wall portion 24 to define the lip of the pan, the latter wall portion being perpendicular to the pan bottom. Collar brackets 26 are provided on the exterior of the wall portion 24 at diametrically opposite points thereof, said brackets comprising strap members which are intermediately offset to provide openings 21 which extend transversely of the plane of the pan bottom. The pan |2 is designed for use as a frying pan.

The pan I3 is relatively deep for use as a stew pan and also has a stepped side structure whereby a circular bottom 3| and an annular portion 32 are defined at opposte sides of a lower wall portion 33 which is conically tapered from the portion 32 to its juncture with the bottom 3|. The upper wall -portion 34 of the pan I3 is perpendicular to the portion 32, and is provided at its free edge with an outturned bead 35 which defines the pan rim. The wall portion 34 mounts a collar bracket 36 at its outer face, said bracket providing an opening '31 which extends transversely of the plane of the pan bottom and is shaped generally as the openings 21 of the brackets 26.

It will now be noted that the perimeter of the upper portion of the pan I3 is smaller than the bore of the upper portion of the pan |2, whereby the former portion and its bracket 31 may be received within the latter portion when the pans are placed in opposition with their cavities registering as in Figures 1 and 4. The closed space thus defined by and between the pans I2 and I3 is arranged to receive the pan M, the members It and H, the burner IS, a pan lifter 38, a cup 39 and plates 40 and 4|, all as arranged in Figure 4.

As illustrated, the plates 4|] and 4| may be nested together and within the pan |2 whereby the flat radial rim portion of the plate 40 may lie flat against the'inner face of the pan portion 22, and the plate 4| may fit generally within the plate 40. Preferably, and as shown, the said plate rim portions are arranged to be respectively engaged with the lips of the pans l4 and I3 when the pan l 2 receives the upper parts of the former pans.

The lifter 38 and drinking cup 39 are disposable in the space defined between the plate ll and the member i7 and the bottom of the pan M, the open side of said cup contacting the top of the stove I5. With the various elements assembled as shown, a flexible strap #32, or other tying element, may be passed through the openings 21 of the brackets 25 on the pan l2 for tightening about the assembly to provide a generally sealed enclosure for the elements within the pans I2 and it which pans thus jointly and solely provide the exterior of the package.

It will now be noted that the pan I4 is generally similar in form to the pan l3 but is slightly smaller for nesting within the latter pan with its bottom 43 against the bottom 3| of the pan l3. A bracket 46, similar to the bracket 36 of the pan i3, is provided at the exterior of the upper wall portion 34 of the pan M, said pan having a conically tapered lower wall portion 45 extending from its annular bottom portion 4'! to the circular bottom at of the pan. Preferably, the outer diameters of the pans i2 and I3 and M at the inner boundaries of the annular pan portions 22 and 32 and 4! respectively are alike, the reason for this relation being hereinafter brought out.

Referring now to the structures of the support members it and i7, it will be noted that both members are generally frusto-conical in outline. At their smaller end portions, the members It and H are stepped inwardly to provide cylindrical collars A8 and 49 respectively extending from radial shoulders 55 and 52. The collar 48 of the member l t is arranged to snugly receive the collar 49 of the member ll whether the members are nested together as in Figure 4 or engaged to provide the support l8 as in Figures 2 and 5 and 8; in the former case, the shoulder 5| of the member it seats against the inner face of the shoulder 52 of the member it, while in the latter case the free edge of the collar 48 engages the shoulder 52 to limit the telescopic engagement of the collars.

At its larger end, the top support member I6 is provided with an outturned head 53, and a wall portion 5 3 adjacent the bead 53 is truly cylindrio with the bore of said portion having the same diameter as the previously mentioned like pan diameters at the inner edges of the portions 22 and 32 and 47 of the pans l2 and I3 and M respectively. In this manner the smaller and bottom portion of any one of said pans may be fittedly engaged within the wall portion 54 and be restrained against lateral displacement while the pan is mounted on the member; the frying pan I2 is shown as being so mounted in Figures 2 and 5,while Figure 8 shows the stew pan l3 similarly mounted on the support assembly I 8.

At its largerend, the member I! is provided with an outturned bead 55 which is arranged to contact any suitable horizontal supporting surface. adjacent the bead 56, and bracket arms 51 extend radially inwardly from said wall portion to jointly provide a support for the burner IS in centered position within the support unit l8. As shown, tongues 58 extend upwardly from the bracket arms 57 adjacent their free ends for centering the burner in its place on the arms 51.

Referring now to the structure of the burner l5, it will be noted that this kit element comprises a receptacle having an annular reservoir space 5! defined therein. A central portion of the An untapered wall portion 56 is provided bottom wall 62 is offset upwardly to define a portion 63 of the inner side wall of the space Bl, said wall portion being cylindrical and longitudinally fluted. The top 64 of the offset is circular and is somewhat smaller in diameter than the cylinder of the wall portion 63, is imperforate, and is connected with the wall portion 63 by meansof an imperforate and conically tapered wall portion 65, it being noted that the portion 64 is substantially midway of the height of the burner.

The top wall 66 of the burner is depressed centrally thereof to provide a portion 61 which may engage flat against the portion 64 of the bottom wall 62. The lower and major portion of the side wall 63 of the depression 69 extends in the line of the reservoir wall 63 as a continuation thereof. Adjacent its upper end, the wall 68 is stepped outwardly to a slight degree to provide a shoulder ll within the space 5!. A tubular wick 12 for effecting a capillary lifting of liquid fuel from the bottom portion of the reservoir space 6| is engaged about the reservoir inner wall portions 63 and 68, and between the shoulder H and the reservoir bottom 62 at the base of the wall portion 63, the installation being permanent. The

wall 6'! at the bottom of the depression -69 is provided with a plurality of openings 73 adjacent its outer edge, said openings communicating with the free space above the sloping wall 65. An annular ring or dam 14 extends upwardly from the wall portion 67 within the circle of openings 13 to define a relatively shallow cup within the depression 69. As shown, the ring 74 comprises an upwardly offset portion of the wall 61.

It will be understood that when the liquid fuel is placed within the depression 59, it will flow therefrom through the openings 13 into the reser-- voir space 6! while leaving a charge of the liquid in the central cup defined within the ring M. The cup comprises a priming cup or fire-pot for effectvaporizing liquid in the wick for burning at the jet openings of the burner.

A circle of jet openings #5 is provided in the receptacle top wall portion adjacent the mouth of the depression 59 whereby gas escaping from the wick and receptacle may be ignited to provide a circle of fire thereat. Outwardly of the circle of jet openings 15, the top burner wall is depressed to substantially the level of the wall portion fil whereby a generally cylindrical top wall portion. 76 is arranged to lie radially outwardly of the upper wick portion in slightly spaced relation thereto. It will thus be understood that the upper wick portion will lie within an annular portion l? of the space 555 which is relatively thin radially thereof, said space normally containing gas only. A limited number of openings 78 are provided in the wall portion 68 slightly below the shoulder "H.

It will now be noted that with a volatile liquid fuel in the reservoir space 6!. for wetting the wick l2, and with a charge of said liquid in the priming cup, a lighting of the priming charge is arranged to produce heat enough to generate gas for escape through the openings 18 and F5 for ignition and burning thereat, the generated gas being progressively ignited at the respective open ings. ducting material, the burning of the gas emitted from the openings 18 and 15 is arranged to'main- With the burner formed of a heat-con tapered whereby its circumference is smaller at the top thereof. A cup-like member 19 is provided for mounting on the annular extension of the burner structure provided by and between the walls 66 and 16, the bore of the member being complementary to the outer face of the wall I6 whereby it may be mounted and frictionally .held on said extension in sealed engagement therewith. the member 19 would be normally mounted on the burner when the same is not in use and may be applied as a snuifer to put out a fire of the burner. This member is also arranged for use as a fuel-measuring cup. With the present burner, which has been designed for burning fuel alcohol or another liquid having approximately the same volatility, each cupful of the liquid will actually provide a predetermined period of burning for the burner, whereby the number measures of fuel placed in the reservoir 6| at a charging thereof will provide a fire for a definitely known time. If desired, a pouring spout may be provided on the cup 19.

To insure a complete use of the amount of fuel placed in the burner, the reservoir bottom 62 preferably slopes downwardly to the base of the wick 12. It will be noted that the fluting of the wall portion 63 provides for a ready flow of the liquid charge from the depression 69. Also, the present burner arrangement involves no valves or other adjustable elements, and the wick 12 is not consumed.

With the described burner structure, the necessary air for supporting the combustion of the generated and discharged gas-must be supplied from the sides of the burner. Accordingly, a series of air inlet openings 8| is provided in the side portion 56 of the member l1, and outlet openings 82 are provided in the wall portion 54 of the member Hi. The two sets of openings 8| and 82 are arranged to each provide total and effective gas passages in such relation to each other and the requirements for a proper and complete burning of fuel at the burner as to insure a maximum use of the generated heat.

Also, the circumferential restriction of the tubular assembly l8 at the juncture of the sections I6 and I1 thereof insures a directing of the inflowing air from the openings 8| centrally over the top line of jet openings 15 for supporting combustion thereat, with the hot combustion products rising and spreading in the section l6 against a pan bottom at its upper end. In this manner, the fullest possible distribution of the generated heat is assured, such being further and materially aided by the extension of the pan bottoms opposite the discharge openings 82 to constrict the effective outlet thereat.

As shown, the air inlet openings 8| are generally triangular, and the material from three of these openings is bent inwardly from the bottom thereof as an integral portion of the member H to provide the burner supporting brackets 51. By reference to Figure 4, it will be noted that, by reason of the extension of the bracket arms 51 within the storage space of the packaged assembly, the member |6 must be removed before the burner l5 may be removed, and vice versa when the kit is being assembled.

The present cooking kit has been designed particularly for outdoor use by campers and travellers, and so must operate satisfactorily in drafty or even windy locations as well as in still air. Accordingly, the circumferential lines of regularly spaced openings 8| and 82 in the assembly |8 are preferably less than a complete circle whereby to leave imperforate areas of the portions 56 and 54, as shown in Figure 2. These closed wall parts may be suitably directed with respect to the direction of air movement whereby the stove may operate properly in a drafty location. Since the members Hi and H are relatively adjustable about their common axis, the imperforate parts of the portions 56 and 54 may be independently adjusted with respect to the air flow against the set up assembly l8.

Referring now to the structure of the pan lifter 38, it will be noted that the latter is arranged to be shapedof sheet metal to have a handle portion 84 of arcuate cross-section, and a fiat head or bit portion 85 which defines an acute angle with the portion 84 and is arranged for insertion in the opening of a collar bracket 26 or 3B or 46 of a pan |2 or l3 or l4 for handling the pan, insertion being effected from the lower end of the opening. The operative application of the lifter is indicated in Figures 2 and 8.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains. While I have described the features and the principles of operation of a structure which I now consider to be a preferred embodiment of my invention, I desire to have it understood that the showing is primarily illustrative, and that such changes may be made, when desired, as fall within the scope of the following claims.

I claim:
